VACUUM-CLEANER.

Specification of Letters Patent.

Patented Mar. 5, 1912.

Application tiled April 6; 1911. Serial No. 619,238.

To all whom it may concern:

. Be it known that I, MICHAEL D. HADJIS- PIRIDIS, a citizen of Turkey, residing at New York, cdunty of New York, State of New York, have invented new and useful Improvements in Vacuum-Cleaners, of which the following is a specification.

This ,invention relates to a portable vacuum cleaning apparatus which is provided with one or more bellows pumps mounted on the device whereby particles of dust can be sucked into a tank carried byv the device. The bellows pumps are secured on and located in a vertical plane with the axis of the vacuum pipe. Each pump bellows is adapted to be actuated and give ose cillatory reciprocating motion in a curvi linear path at right angles to the axis of the vacuum pipe. The pumps communicate with a vacuum pipe and when operated force the air out of the said pipe and create a suction at the mouth of the nozzle thus sucking any particles of dust or dirt lying in the vicinity of the inlet`nozzle into the collecting tank. The device is equipped' with a stirrup having a yielding connection attached to the vacuum pipe which tends to force the mouthof the nozzle toward the floor while the device is operated.

The novel features of the invention are more fully described in the following specification and claims and illustrated in the accompanying drawings in which:

Figure 1 represents a side 4elevation partly in section of an apparatus embodying this invention. Fig. 2 is a detail section showing the lower valve mechanismz In this drawing the letter a designates a tank having a lgwer inlet pipe b and -an The lower portion of the tank is closed by a cover a which is adapted to be bolted or screwed to the tank so that the cover can be readily removed.

To the lower end of the inlet pipe is attached1 in any suitable way a nozzle d adapted'to communicate with the said tank.

To the upper portion of the' vacuum pipe is secured a pair of bellows pumps e and f having inlet pipes g and L leading into the said vacuum pipe. The operating parts of each of these pumps is arranged-in a line with the axis of the vacuum pipe and each vbellows is provided with a'handle z' and j whereby the'bellows can be manipulated. The upper end of the vacuum pipe has a handle k whereby the device can be carried when not in use, or when only one pump 1s operated the handle can be utilized to hold A and guide the device.

,In the interior of the tank is pl'aced a bag mwvith its mouth facing the lower portion of the tank. This bag is reticulated to allow the air to pass through the interstices of the fabricand is moistened so that any particles of dust will cling to the interior of the bag. The bag is covered with a porous fabric m so that when the bag is jammed in place in the tank it will not be apt to shift its position. To the lower portion 'of the vacuum pipe is attached a spring n to the lower end of which is suspended a stirrup o adapted for the insertion of a foot so that veo the apparatus may be steadied at the desired angle.

Each bellows pump is equipped with one or more flap valves p adapted to open out- 'wardly and allow the air to be expelled from the interior of the pipe when the pump is in operation. The lower interior portion ofthe vacuum pipe is provided with a valve q of suitable construction to normally rest on a seat 1' formed in the vacuum pipe.

The operation of the apparatus 1s as follows: When the pump is oscillated to compress thc bellows it forces the-air in the vacuum pipe out at the valve p the valve q in the meantime remains closed until the pump is again oscillated to eX and or extend the bellows the air then un er thevalve y9* opens the valve and rushes into the pipe thus creating a suction at the mouth of the nozzle.

The parts of the device such as the tank with its pipe connections may be made of aluminum or other light metal so that the device can be carried with ease.

I claim:

1. A vacuum cleaner comprising a tank l'havin a dependi-ng'nozzle, a vacuum pipe exten ing upwardly from the tank, devices operatively carried by the vacuum pipe lfor creating a suction at the mouth of the nozzle, and steadying l means connected to the vacuum pipe adapted to force the mouth of the nozzle toward th'e floor.

2. A vacuum cleaner comprising a tank havin a depending nozzle, a vacuum pipe exten ing upwardly from the tank, devices operatively carried by the vacuum pipe for creating a suction at the mouth of the nozzle, and an adjustable steadying device depending from the vacuumpipe for engagement With the oor adapted to yieldingly hold the nozzle against the ground.

3. A. vacuum cleaner comprising a tank having a depending nozzle, a vacuum pipe extending upwardly from the tank, devices operatively carried by the vacuum pipe for creating a suction at the niouthof the nozzle, a spring connected to the vacuum pipe, a stirrup suspended from the lower end of the spring for engagementwith the foot of an operator and ada ted to hold the` nozzle against the groun l In testimony whereof E have hereunto set my hand in the presence of two subscribing Witnesses.
